SA-333 Gr 6 · Low-temperature carbon steel pipe
An ASTM A333 Gr 6 bend is a pipe bend with a larger radius than a standard elbow, for use with ASTM A333 Gr 6 pipe. ASTM A333 Gr 6 itself is a pipe or plate specification, so the matching bend is made to ASTM A420 WPL6 — which is what we supply for A333 Gr 6 lines. Bends of 3D, 5D and larger radius give smoother flow than elbows and suit slurry, pigging and pipeline service. They are induction- or cold-bent from pipe.

ASTM A333 Gr 6 Bend: Why A333 Gr 6 for bends
Bends of 3D, 5D and larger radius give smoother flow than elbows and suit slurry, pigging and pipeline service. They are induction- or cold-bent from pipe. In ASTM A333 Gr 6, the choice usually comes down to the medium and temperature — the rows here are the points buyers check for this exact combination.
| Why this grade | Carbon and low-alloy fittings suit hydrocarbon, steam and utility lines. ASTM A333 Gr 6 is picked for cold-climate and refrigerated piping down to −45 °C. |
|---|---|
| Typical service | LNG & refrigeration — Cold process lines. |
| Welding to carbon steel | Matching carbon or low-alloy filler is used; joints to stainless need ER309L |
| Matching filler | E7018-1 / ER80S-Ni1 |

Other ASTM A333 Gr 6 pipe fittings
ASTM A333 Gr 6 Bend — questions buyers ask
Bend or elbow — what is the difference?
An elbow has a fixed 1D or 1.5D radius to ASME B16.9; a bend is bent from pipe to a larger radius, typically 3D or 5D.
Can ASTM A333 Gr 6 bends be welded to carbon steel?
Yes — matching carbon or low-alloy filler is used; joints to stainless need ER309L.
Which standard covers ASTM A333 Gr 6 bends?
The material is ASTM A420 WPL6; dimensions follow ASME B16.49 · project specs. Always state both on your purchase order, with the edition if your project specifies one.
What decides the price of a ASTM A333 Gr 6 bend?
The steel price, the size and schedule or class, quantity, and the testing and documents required. Send your list and we quote the same working day.
What documents do you supply?
EN 10204 3.1 or 3.2 certificates available on request / as specified in the PO; dimensional reports as required. PMI can be arranged depending on product and requirements, as specified in the PO.
